Bandra Garib-Rath - नाम से गरीब, लेकिन मेरे दिल के करीब - Abdul Rehman

Does anyone has the correct info about rake sharing of this train with other bi-weekly trains?
Info on this website is mess here!!
It says that 17017/18 shares its rake with 17001/01 and 17037/38.
for 17037/38, it says that it shares rake with 17017/18.
but...
more...

for 17001/02 it says that it shares its rake with 17007/08.
and for 17007/08 it says that it shares its rake with 12769/70.
Coach composition is same only for 17001/02, 17007/08 and 17037/38 (PC is extra in this one). Other 2 are totally different.
